The surprising discovery of a massive, Milky Way–size galaxy that is made of 99.99 percent dark matter has astronomers dreaming up new ideas about how galaxies form.
The first star map from the ESA’s Gaia space telescope is poised to revolutionize our understanding of the Milky Way galaxy.
How do scientists react to major breaking science news? For astrophysicists after the big gravitational waves announcement, it was meeting for two weeks in Santa Barbara, California.
Just months after their discovery, gravitational waves coming from the mergers of black holes are shaking up astrophysics.
The astrophysicist Tracy Slatyer is searching for faint wisps of dark matter annihilating in the early universe — and perhaps in hiding places closer to home.
The spokesperson for the Laser Interferometer Gravitational-Wave Observatory called it “a promising start to mapping the populations of black holes in our universe.”
What could cause galaxies millions of light years apart to all spew material in the same direction?
The astrophysicist, conceptual writer and host of standing-room-only scientific soirees at a repurposed factory in Brooklyn sees science as a powerful force in culture.
In the new, free-for-all era of dark matter research, the controversial idea that dark matter is concentrated in thin disks is being rescued from scientific oblivion.
